The Hammond typewriter has a brilliant mechanical design and a stunning look, encased in cherry (was also available in oak and mahogany) with ebony keys. One might well imagine that with the name Hammond and with ebony piano like keys, that there would be a connection with the Hammond Organ Company but there is none.
Instead of using type bars, a split type-shuttle with hardened rubber characters rotates each way into position as the keys are pushed. Then a spring-loaded hammer swings from behind the carriage, striking the paper and ribbon against the type-shuttle to print. The constant force of the hammer gives an even impression to each character typed, regardless of how soft or hard the keys are pushed.
The type-shuttle is readily interchangeable, allowing for different fonts and languages. There were hundreds of choices available. “For every nation, for every tongue” was the slogan Hammond used to convey this versatility. One drawback in the design of the Hammond is in the extra effort required to load a new sheet of paper into the carriage. As the striking hammer is positioned behind the platen and obstructs the normal paper exit, paper is loaded into a cylindrical holder under the platen before typing. Then the paper is fed out line-by-line as one advances the page.
The Hammond sold for $100, a common price for a full sized keyboard typewriter of the day but still a lot of money as a cast iron coal burning furnace could be bought for $50.
The intriguing device, shown in the third period advertisement below (1890 Scientific American), allows one to operate the shift and space keys with ones knees and the carriage return with ones foot.
